Useful guides
Best Washing Machine Setting for Everyday Laundry
A useful everyday routine starts by sorting the load, then choosing the fabric programme in the manual. A Mixed or Easy Care setting is a candidate for compatible clothing, not a universal default.
Best Washing Machine Setting for Towels
For suitable cotton towels, Cottons or a dedicated Towels programme can be appropriate. Follow the towel label: 40°C may suit routine washing, while 60°C is only an option for textiles and programmes that permit it.
Clothes Still Dirty After Washing Machine
Poor wash results do not identify a particular failed part. Check the load, fabric programme, stain treatment and detergent instructions, then investigate any actual fault or failure to rinse or drain.
